A new technology has found it’s way to transmit information through light instead of wires. This allows to transmit 8 terabits of data per second, which is the equivalent of around 5 000 high-definition movies, per second.
So far, the biggest advantage of this technology is his power consumption, which is 100 times less than on wire. Although new technologies as such takes time to hit the market, this one as bigger chance to hit it pretty soon, as IBM researcher Clint Schow explain:

These aren’t theoretical experiments or chips sitting in unique conditions in a lab, but rather chipsets that could hit the market in the next two years. The innovation lies in the fact that we are making optics with the same kind of packaging as electronics.
